Embodiments of the invention include a Clustered Shared Volume File System (CsvFs) that appears to clients as a local file system. The CsvFs communicates to a node where a disk is mounted to coordinate access to files on the disks. CsvFs uses Opportunistic Locks (oplocks) to decide when direct access to a volume is safe. CsvFs can be extended with oplock upgrade mechanisms that allow a coordinating node to tell CsvFs when it is safe to attempt to upgrade oplock. CsvFs also uses a transitivity property of oplocks to be able to grant (delegate) oplocks to clients that are on top of CsvFs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Volumes and file system in cluster shared volumes","description":"The present invention extends to methods, systems, and computer program products for sharing volumes between clustered nodes.
